Excess crankcase pressure (sometimes known as "blow-by") is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This re-circulated air contains aerated oil from the crankcase which is burned by the engine. Supercharged, nitrous boosted and high mileage engines often draw excessive amounts of oil into the engine through the PCV system. The Steeda oil separator plugs into the PCV hose between the PCV valve and the intake manifold and removes aerated oil from the re circulated air and collects it in a tube that can be drained and recycled.

Oil separator kits include the oil separator and all required hardware.

A must have!
This is a must have for any turbo application. The price is perfect. Installation was a breeze, I did it at work on my lunch break!
